To all whom/it 'may concern: Y

Be it known that I, WILLIAM JAQUIERY, a

citizen of the United States, and resident of the city of Providence, in the county ,of

,Providence and State of Rhode Island, have invented certain new and useful Improvements in Snap-Fastener Studs, of which the following is a Specification.

This invention relates to snap fastenerV studs; and has for its object to provide a spring cage member, and a member extending intosaid cage to support the top of the same against acrushing action.

With these and otherobjects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings: Figure 1- is a side elevation showing my .improved fastener Vstud with the anvil or supporting member inserted therein.

Fig. 2- is a sectional elevation showing the cage member and the anvil or supporting member inserted into the cage to support the same against a crushing action; also show-v ing the rivet or post member as inserted and locked in the anvil member.l i

Fig. 3 shows `the anvil member in elevation.

Fig. 4- shows the post or rivet member in elevation. A lReferring' to the drawings,r10 designates the cage member Vwhich is made of fiat spring stock having a plurality of arms 11 f connected together at 12. These arms are bent to formsubstantially a sphericallyshaped body,`the free ends of the arms being turned outwardly forming radiating feet 13. By this construction the walls of the cage member are permitted to yield when pressed into the socket member of the fastener (not shown).

It is found in practice that any undue pressure on theouter end or top portion 12 of'this cage' member will crush and easily destroy the same. To obviate'this difficulty I have provided a support or anvil member 14 which is preferablymade in tubular form having an annular flange 15 engaging the under side of the feet 13 0f the cage arms4 thebody portionrof this anvil member being Specification of Letters Patent. Patented B131', 29, 1921. Application led October 2 0, 1919. Serial No. 331,949.`

designed to extend from the bottom of the feet 13 upwardly, its outer end 16 engaging theA under side of the ,top wall 12 to firmly support the same against a crushing action. l In order to secure the feet 13 to the fiange 15 I have provided a collar 17 which extends over the top of the feet and is then folded around beneath `the flange l15 binding these two securely together.

In order to secure this` stud member to the fabric or material 18011 which it is designed to be carried it is found necessary to provide a tubular rivet or post 19 having a flange 23, said post being made of soft or readily vb'endable, or crushable material and of suicient length so that when it is forced into the tubular anvil member its upper end 20 will engage the 'upper end wall of the anvil, Vand `the post will be crushed and enlarged in different places along its length, as illustrated in Fig. 2; Y

To accomplish Vthe locking of this post 17 in the tubular anvil, I have provided inwardly-extending portions 21 in the side walls of this Vanvil body, which portions may be made in the form of annular ribs or in any other desired shape yto engage the outwardly-extending .portions 22 of the wall of the rivet or post due to the crushing action to lock the'two members together thereby attaching the stud member to the fabric or material 18. y

My improved `snap fastener is simple and inexpensive and most practical in construction and by its use the positive support in the case renders the latter practically indestructible against any pressure which may be brought against the end thereof.

The foregoing description is directed solely toward the construction illustrated, but I desire it to be understood'that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

1.3A snap fastener stud comprising an outer spring cage member, a tubular anvil member extending into saidv cage its inner end engaging the top wall of said cage to base of Said cage, andlmeans in said anvil cage, the outer end of said anvil being member vfor engaging and locking a rivet or flanged and attached tothe base of said cage 10 post when forced thereinto. said anvil being provided with inwardly-ex- Y 2.
